Madhan Neethiraj resolved ATLAS-1713.
-------------------------------------
    Resolution: Invalid

[~ssainath] - when a type is has references from other types, it will not be possible to delete the type before deleting the types that reference this type. And it is possible for the types involved to have reference to each other - like hive_table & hive_column. And API that deletes a single type will not be a handle such cases. Hence the API that takes AtlasTypesDef, where all types to be deleted can be specified.

[~davidrad]
bq. I suggest that we should only allow a delete of a type that has no associated active instances.
bq. if there are relationships to / from other types - then potentially those other types are invalidated by the deletion of this type.
These were implemented in ATLAS-1673.

bq. I assume we will soft delete a type - so it is still present in the graph.
Type deletes are allowed only when no entity or other type references the type. The request for type delete is usually to get rid of classifications created by users (like testTag, testing, ..). Given this, do you think soft-delete of types is a high priority/critical item?

> Since type has both name and guid , it could be given as path instead of sending the whole type definition as body.
